Data from DeGolyer, Volume 57, pp. 311+. See also P Allen Copeland, "Baldwin 0-6-6-0 Locomotives Sent to Chile", unpublished manuscript dated 6 June 2009, supplied by Allen Stanley in August 2013 from his extensive Rail Data Exchange collection and Martin Coombs, Chilean steam locomotive list, Part 2, Standard, 4' 6", 4' 2" and 3' 6" locos, 2018, pp98-100 downloaded from []. Works numbers were 46494-46497, 46529 in September 1917 and 46531, 46603-46604 in October, 46605 in November.
The onset of the Russian Revolution in November (Julian date: October) 1917 led to the cancellation of orders for hundreds of locomotives, including a batch of 51 light Mallets. All but one found new owners. After Baldwin placed them with the General Equipment Company, the broker sold nine to the Andean Anglo-Chilean Consolidated Nitrate Corporation (ACN) to run on the FCTT. FCTT; each engine cost $47,500. These had been numbered 101-105, 107-110 for the Russian Government.
Copeland was able to confirm that the ACN road numbers for the first five were the same, but could not be sure of the last four. Coombs's extensive history of Chilean locomotives, published in 2018, contends that most of the batch could be vouched for. Photos show the very short tender trailing the engine under which a leading single axle and a bogie carried the load. Another photo shows one of the class trailing an additional auxiliary tender.
